ALEXA SXT Software Update Package 1.0 for ALEXA SXT (SUP_AlexaSXT_1.0_36225)

October 24, 2016

Release Notes - ALEXA SXT Software Update Package 1.0 of 26

A. Introduction We are happy to announce that Software Update Package (SUP) 1.0 is now available as a download for the ARRI ALEXA SXT cameras. This document describes new features and changes that are introduced with ALEXA SXT SUP 1.0 in contrast to ALEXA XT SUP 11.1.1 Useful references can be found at the end of this document: ALEXA Maximum Frame Rates ALEXA Maximum Frame Rates – Overview ALEXA Data Rates

New Features Overview A more detailed description of each feature is given in the section 'New Features and Changes'.

New Recording Formats, including ProRes 4K ALEXA SXT cameras offer seven new recording formats to provide the most efficient recording options for any production. In addition to a new sensor mode (6:5 for plug-and-play anamorphic shooting), all sensor modes (16:9, 6:5, 4:3 and Open Gate) are now available in ARRIRAW and ProRes. The two new ProRes recording formats ‘6:5 ProRes 2K Anamorphic’ and ‘6:5 ProRes 4K Cine Anamorphic’ provide the easiest method to shoot anamorphic, as the camera already de-squeezes the image to a 2K or 4K Cine format. The new ProRes recording format ‘4:3 ProRes 2.8K’ offers the same pixel count as 4:3 ARRIRAW 2.8K with a lower data rate.

New ARRI Look Management The new ARRI Look Management offers a comprehensive look management from pre-production to post-production.

Super flexible on-set monitoring ALEXA SXT cameras offer High Dynamic Range (HDR) monitoring and four independent monitoring outputs which are usable either as Rec 709 or Rec 2020 output. Frame grab options have been greatly improved.

Improved image quality Includes optional mild ARRI Noise Reduction (ANR), advanced defect pixel correction and 3D LUTs.

Single speed mode All framerates are now available in one single speed mode.

New media bay and drives The ALEXA SXT media bay is capable of supporting SxS PRO, SxS Pro+, CFast 2.0, XR Capture Drives and SXR Capture Drives. The new SXR Capture Drives are modern high capacity (1 TB and 2 TB) and high speed drives. ALEXA SXT offers redundant recording (RAID) to XR and SXR Capture Drives.


Update Information Cameras should always be running the latest SUP release version as this allows you to benefit from the latest improvements, features and bug fixes. We do not, however, recommend installing a new SUP in the middle of a production. Please note that ALEXA SXT SUPs should only be installed on ALEXA SXT cameras, and are not compatible with ALEXA Classic, ALEXA Classic cameras with the XR Module upgrade and ALEXA XT cameras. Warning: Do not install the SXT SUP onto a camera model it is not made for! Do not attempt to install these SUPs on ALEXA HD, ALEXA HD Plus, ALEXA Fiber Remote, ALEXA Fiber Remote Plus, ALEXA Classic, ALEXA Classic with the XR Module upgrade or ALEXA XT cameras! Doing so may cause the camera to malfunction and become inaccessible. If that happens, the camera can only be made accessible with the support of an ARRI Service Center. Similarly, SUPs for the older ALEXA cameras should not be installed on the ALEXA SXT cameras.

Downgrading As this is the first ALEXA SXT Software Update Package, it is not possible to revert back to a previous release version.

Additional Software Please note that when recording XR Capture Drives or SXR Capture Drives in the ALEXA SXT, one must always use the Codex Production Suite 4.1 software. The older Codex dts 3.x software may not be used anymore; while it seems to work with XR Capture Drives recorded in an ALEXA SXT, it creates a number of significant problems as it does not understand the metadata properly. The ARRIRAW Converter and SDK 5.3 are not affected and do not cause a problem. Customers who purchase a new XR or SXR Thunderbolt Capture Drive Dock will receive the Codex Production Suite 4.1 for free. Owners of older Capture Drives docks can sign up on the Codex website (codex.online) for a version of the Production Suite 4.1 that includes a 30 day trial of the full Production Suite. After 30 days the customer can purchase a 12-month Codex Connect subscription, which includes the full Production Suite. Even without the Codex Connect subscription, the software will retain the basic functionality of downloading ProRes and ARRIRAW files.

Electronic Viewfinder and/or MON OUT Smooth mode is now available in all sensor modes up to 30 fps.

General No changes.

Imaging No changes.

Image Processing

New ARRI Look Management The color and look management system that has been devised for AMIRA and ALEXA Mini have now been expanded for ALEXA SXT. We call this system ARRI Look Management. This highly refined, powerful and flexible system will be used in ALEXA SXT, ALEXA Mini, AMIRA and future cameras to accommodate the evolving need for accurate color and look management on-set, near-set and in postproduction. The new ARRI Look Management works with the new ARRI Look File ALF-2 which includes 3D LUT, CDL values and the name of the target color space. ALF-2 files can be created using the new ARRI Color Tool, which can also import and export 3D LUTs in many formats. All created looks are always stored in metadata, which makes it even easier to do live grading on-set, automated dailies and editing with looks. A large number of third parties are using the ARRI look management library to include ARRI Look Management features into their products and to communicate to the ALEXA SXT camera via the ARRI Camera Access Protocol (CAP). Below is a workflow diagram showing how the ALEXA SXT can replace a LUT box on set and make the entire look workflow simpler, faster and easier. For a detailed tour of the new ARRI Look Management, we will soon publish a white paper on the ARRI website.

Improved Image Quality With the help of more powerful imaging hardware and completely overhauled imaging software ALEXA SXT now offers an advanced pixel correction, optional mild ARRI Noise Reduction (ANR) for high sensitivity and 3D LUTs provide more flexibility for baked in looks. The ANR will be turned off by default.


Inputs No changes.

Recording

Seven New Recording Formats ALEXA SXT cameras offer seven new recording formats (shown in blue text in the table below) to provide the most efficient recording options for any production. In addition to a new sensor mode (6:5 for plug-and-play anamorphic shooting), all sensor modes (16:9, 6:5, 4:3 and Open Gate) are now available in ARRIRAW and ProRes. The new formats are described in detail below.

6:5 Sensor Mode MENU>PROJECT>SENSOR MODE>6:5

The 6:5 sensor mode (formerly 4:3 Cropped) is used most often for feature films and commercials shooting with anamorphic lenses and is crucial for delivering the unique and cinematic widescreen look that can


trace its origins back to the CinemaScope films of the 1950s. It is a look that has long been appreciated by cinematographers, directors and the viewing public. Since anamorphic lenses squeeze the 2.39:1 image by a factor of 2, the resulting area used on the sensor has a 1.195:1 aspect ratio, which is 6:5. For convenient viewing of anamorphic images an anamorphic de-squeeze license is included with all ALEXA SXT cameras. The ALEXA sensor is unique in that it has the same height as a 35 mm film frame, and so anamorphic lenses exhibit the same field of view as on 35 mm film. The 6:5 sensor mode can be recorded in ARRIRAW or ProRes on ALEXA SXT cameras.

Recording Format '16:9 ProRes 4K UHD' MENU>PROJECT>SENSOR MODE>16:9 MENU>RECORDING>FORMAT>ProRes MENU>RECORDING>RESOLUTION>4K UHD

'16:9 ProRes 4K UHD' is the easiest and fastest path to the best overall image quality for any 4K UHD TV production. The camera uses 3.2K from the sensor with a mild 1.2x up-sample to record a 4K UHD (3840 x 2160) image. This is the same active image area and recording format as used by the ALEXA Mini and the AMIRA

Recording Format 'Open Gate ProRes 4K Cine' MENU>PROJECT>SENSOR MODE>Open Gate MENU>RECORDING>FORMAT>ProRes MENU>RECORDING>RESOLUTION>4K Cine


'Open Gate ProRes 4K Cine' is the easiest and fastest path for 4K DCI cinema. This recording format is only available in ALEXA SXT and benefits from the immediacy and speed of ProRes workflows. It is using an active image area of 3414 x 2198 (instead of 3424 x 2202 like the other Open Gate formats) since that provides a better re-sampling factor to 4096 x 2636.

Recording Format '6:5 ProRes 2K Anamorphic' MENU>PROJECT>SENSOR MODE>6:5 MENU>RECORDING>FORMAT>ProRes MENU>RECORDING>RESOLUTION>2K Anamorphic


'6:5 ProRes 2K Anamorphic' is the most economical path to best overall image quality with anamorphic lenses for a 2K deliverable. In addition to the immediacy and speed of the ProRes workflow, 6:5 sensor mode captures only the sensor area needed for anamorphic lenses, thus avoiding cropping steps in post and providing an increase in frame rate versus 4:3 sensor mode. Additionally, the camera already debayers, down-samples and de-squeezes the anamorphic image to record a ready to view image in the 2K DCI delivery format (2048 x 858).

Recording Format '6:5 ProRes 4K Cine Anamorphic' MENU>PROJECT>SENSOR MODE>6:5 MENU>RECORDING>FORMAT>ProRes MENU>RECORDING>RESOLUTION>4K Cine Anamorphic

'6:5 ProRes 4K Cine Anamorphic' is the most economical path to best overall image quality with anamorphic lenses for a 4K deliverable. In addition to the immediacy and speed of the ProRes workflow, 6:5 sensor mode captures only the sensor area needed for anamorphic lenses, thus avoiding cropping steps in post and providing an increase in frame rate versus 4:3 sensor mode. Additionally, the camera already debayers, up/down-samples and de-squeezes the anamorphic image to record a ready to view image in the 4K DCI delivery format (4096 x 1716).

Recording Format ‘4:3 ProRes 2.8K’ MENU>PROJECT>SENSOR MODE>4:3 MENU>RECORDING>FORMAT>ProRes MENU>RECORDING>RESOLUTION>2.8K


‘4:3 ProRes 2.8K’ has the same pixel count as ‘4:3 ARRIRAW 2.8K’ and offers extra height for VFX tracking markers and repositioning of the image. ‘4:3 ProRes 2.8K’ will be mostly used for spherical 16:9 or 1.85:1 (rectangle with red dotted line in the image above) shows. This format is covered by lenses with smaller image circles than Open Gate.

Recording Format '16:9 ARRIRAW 3.2K' MENU>PROJECT>SENSOR MODE>16:9 MENU>RECORDING>FORMAT>ARRIRAW MENU>RECORDING>RESOLUTION>3.2K

'16:9 ARRIRAW 3.2K' is the ARRIRAW format with the largest pixel raster that also fits inside the image circle of most ARRI Super 35 PL mount lenses AND reaches 120 fps. As such it does not suffer the data load of 4K, yet there is enough resolution for padding or up-sampling. The exact recording resolution of 3168 x 1782 (which is slightly different from the ProRes 3.2K recording resolution of 3200 x 1800) was necessary to make 120 fps recording possible.

Recording Format 'Open Gate ProRes 3.4K' MENU>PROJECT>SENSOR MODE>Open Gate MENU>RECORDING>FORMAT>ProRes MENU>RECORDING>RESOLUTION>3.4K


'Open Gate ProRes 3.4K' captures the full sensor area, but in contrast to 'Open Gate ARRIRAW 3.4K', this format performs the debayering step inside the camera to record a color ProRes image (3424 x 2202).

'16:9 ProRes 3.2K' Change The recording resolution of 16:9 ProRes 3.2K in ALEXA SXT has been changed to 3200 x 1800, so it is the same as in ALEXA Mini and AMIRA. Please note that the recording resolution of 16:9 ProRes 3.2K in ALEXA XT is 3200 x 1782 with an active image area of 3164 x 1778 pixels.

Lenses No changes.

Media Access No changes.

Metadata/Time Code The ALEXA SXT will record appropriate Metadata for all new features including new recording formats and the new ARRI Look Management. For a detailed tour of the ARRI Metadata, see the white paper ‘ARRI Metadata White Paper for ALEXA SXT SUP 1.0’ that will be published soon on the ARRI website.

Optical Viewfinder No changes.

Outputs

Super Flexible On-set Monitoring: Four Independent Outputs COLOR>EVF/MON PROCESSING


MENU>MONTORING>MON OUT 1>

COLOR>MON COLOR SPACES

ALEXA SXT has four independent monitoring outputs: EVF-1, MON OUT 1 (+ MON OUT 1B on Plus and Studio, which is simply a clone of MON OUT 1A), MON OUT 2 and MON OUT 3. It is possible to apply independent settings to each of them: • Independent image processing • Independent surround view, status info, peaking, false color, etc. • Independent monitor color space There is one exception in independency of the monitoring outputs, MON OUT 2 and MON OUT 3 are not independent from each other regarding the frame rate of the output. It is only possible to assign one mutual frame rate to MON OUT 2 and MON OUT 3.

Super Flexible On-set Monitoring: Better frame grabs MENU>FRAMEGRABS


Frame grabs are now possible in all sensor modes and will include the image area of the recording format without any frame lines, status info, peaking or false color superimposed. The source of the frame grab can be freely assigned: either as .jpeg, .tif or .dpx from one of the three monitor outputs (MON OUT 1, 2 or 3) or as a .ari from a step earlier in the processing chain where the image is available in ARRIRAW in the full resolution of the recording format.

Recording Media

New Media Bay and Drives ALEXA SXT accepts four types of recording media: • CFast 2.0 cards via CFast 2.0 Adapter 2 • SxS PRO and SxS PRO+ cards via SxS Adapter 2 • XR Capture Drives via XR Adapter • SXR Capture Drives via SXR Adapter SXR Capture Drives are available in high capacities of 1 TB or 2 TB which leads to longer recording times with a fast maximum write speed of 20 Gb/s. SXR Capture Drives are compatible with ALEXA SXT and ALEXA 65 cameras.

Supported Media in ALEXA SXT SUP 1.0: • SXR Capture Drives 1 TB and 2 TB • XR Capture Drives 512 GB • SxS PRO cards 64 GB (SBP-64A) • SxS PRO+ cards 64 GB (SBP-64B & SBP-64C) and 128 GB (SBP-128B & SBP-128C) • LEXAR 3600x CFast 2.0 cards 256 GB Note 1: Support for SxS PRO+ 256 GB cards (SBP-256D) is planned for a future SXT SUP.

Media not supported anymore with SXT SUP 1.0: • SxS PRO 8, 16 and 32 GB cards • All CFast 2.0 SanDisk cards • LEXAR CFast 2.0 128 GB cards


Clearing Data Options for Recording Media There are two methods for clearing old data from a recording medium with ALEXA SXT cameras: Quick Format and Erase. For technical reasons, most media allows only one of those methods. Quick Format erases only the file allocation table, but leaves the actual data still on the card. Quick Format is therefore the faster method. Erase takes longer than Quick Format, but ensures that all data on the card is erased. Using Erase with SxS PRO/PRO+ cards can increase their write speed.

Redundant Recording for ProRes on XR and SXR Capture Drives In ALEXA SXT cameras, ProRes is always recorded with a method (RAID) that provides redundancy for greater data security for both XR and SXR Capture Drives. As with ALEXA XT cameras, half the Capture Drive's capacity can be used to record ProRes, but with the SXT, the other half can be used to increase the safety of the recorded data.

ProRes RAID for XR Capture Drives When XR Capture Drives are being formatted for ProRes in the ALEXA SXT, they are being formatted as a RAID 1 (mirrored) volume. XR Capture Drives contain two internal SSD drives, and with RAID 1 the same ProRes data is written onto each of those two drives.

ProRes RAID for SXR Capture Drives When SXR Capture Drives are being formatted for ProRes in the ALEXA SXT, essentially the same happens, but since SXR Capture Drives contain four internal SSDs, a combination of RAID 1 (mirroring) and RAID 0 (striping) is used, commonly referred to as RAID 10. Drives zero and one will be combined into one RAID 1 volume and drives two and three into another. This provides redundancy. The resulting two RAID 1 volumes are combined into two RAID 0 volume so it appears as one volume.


Downloading ProRes RAID Data In order to download ProRes from XR and SXR Capture Drives that have been formatted and recorded in an ALEXA SXT, the ARRI RAID driver has to be installed on the Mac that the dock is connected to. The ARRI RAID driver is provided as part of the Codex Production Suite 4.1 software and is necessary to read ProRes from XR and SXR Capture Drives recorded with the ALEXA SXT. Make sure to select the “Capture Drive RAID support” option while installing the software. If your software does not provide that option, please contact ARRI at [email protected].

Notes CAUTION! RAID redundancy is very helpful if data from one of the two internal drives is corrupted or one of the internal drives is damaged. But the XR or SXR Capture Drive still appears as one volume, and if it gets erased accidentally by the user, the data is gone. CAUTION! While this redundancy is a great new feature, it creates some incompatibilities you should be aware of: • Please note that due to the camera’s write pattern, there may be gaps in the clips which do not contain

valid QuickTime data. These gaps may not be bit-identical on the individual SSDs unless the drives have previously been erased using the Codex Vault. This is normal and only relevant in cases where the data has to be restored manually.

• If an XR or SXR Capture Drive that has been formatted on an ALEXA SXT should be downloaded on a Mac that does not have the ARRI RAID driver installed, the Mac cannot recognize the RAID formatted drive and will ask if this drive should be formatted. Don't format the drive, but install the ARRI RAID driver and try again.

• If an XR Capture Drive that has been formatted for ProRes on an ALEXA XT is then placed into an ALEXA SXT, the ALEXA SXT will not be able to read the drive and will ask if the drive should be formatted.

• If an XR Capture Drive that has been formatted for ProRes on an ALEXA SXT is then placed into an ALEXA XT, the ALEXA XT will only be able to see one of the two internal drives, and will therefore also only be able to format one of the two drives. Data may be left over on the other internal drive from the use in the ALEXA SXT. In order to avoid this, make sure to erase XR Capture Drives by formatting them in the ALEXA SXT or with a Mac at the end of your production.


ProRes RAID FAQ Q: What does RAID mean? A: RAID (redundant array of independent disks) is a data storage technology that combines multiple physical disk drives into a single logical unit for the purposes of data redundancy, performance improvement, or both. Of the many RAID types available, we use RAID 0, RAID 1 and RAID 10 in ALEXA SXT. • RAID 0 consists of striping, where multiple single disks are combined into a single volume. The capacity

of a RAID 0 volume is the sum of the capacities of the disks in the set.

• RAID 1 consists of data mirroring, where data is written identically to two (or more) drives, thereby producing a "mirrored set" of drives.

• RAID 10 is a nested (hybrid) RAID type, where two disks create a mirrored RAID 1 volume, and then two of those volumes are combined into one logical RAID 0 volume. In most cases RAID 10 provides better throughput and latency than all other RAID levels except RAID 0.

Q: Can I turn the ProRes redundancy function off? A: No, in ALEXA SXT cameras, both XR and SXR Capture Drives always use RAID redundancy when recording ProRes. Q: Is this redundancy also available for ARRIRAW recording? A: No, at this point in time Capture Drives have proven to be very reliable, so we do not think this is necessary.


Q: So why did you provide RAID for ProRes, then? A: For technical reasons, ARRIRAW can use the full capacity of the Capture Drive, while ProRes can only use half of the drive's capacity. Rather than let half the drive go to waste when recording ProRes, we thought we might use this free capacity to add some data safety, even though Capture Drives are already one of the safest media available. This also makes sense as ProRes has a lower data rate than ARRIRAW, and so much more ProRes can be recorded onto a single drive than ARRIRAW, especially now that 1 TB and 2 TB Capture Drives are available Q: Is this redundancy also available for SxS PRO, SxS PRO+ and CFast 2.0 cards? A: No, the RAID redundancy is only available for XR and SXR Capture Drives in the ALEXA SXT. Q: Is there an ARRI RAID driver for windows? A: No. Since the SXR Capture Drive dock only works in conjunction with Codex software and there is no Codex software for Windows, a Windows ARRI RAID driver would make no sense.


Remote Control/3D No changes.

User Interface

Peaking ALEXA SXT now has a peaking focus check based on horizontal and vertical structures of the image. ALEXA Classic and XT cameras have a peaking only based on horizontal structures of the image.

Single Speed Mode With Single Speed Mode in ALEXA SXT SUP 1.0 it is now possible to change framerates between 0.75 fps and 120 fps without changing speed mode and without rebooting the camera.

Support for ALEXA user buttons 4, 5 and 6 from WCU-4 It is now possible to control not only User Button 1, 2 and 3 from the WCU-4, but also User Button 4, 5 and 6.

Capture Drive info on camera display INFO>MEDIA INFO

In MEDIA INFO now also the Firmware version of the Capture Drive is available.

Factory reset default The factory reset default setting is now 23.976 fps and 180° shutter angle.


C. Known Issues

ALEXA Studio

• Mirror HW error The ALEX SXT Studio can show a "Mirror HW error. Please contact service" sometimes. Don’t worry, just reboot or move the mirror from [G]ate to [V]iew or vice versa.

Accessories

• WCU-4 only supports MON OUT 1 WCU-4 functions Monitor Peaking, Surround, False Color, Status Info and Framelines are only functional on MON OUT 1. MON OUT 2 and 3 are not supported.

• LBUS lens motors are not compatible with ALEXA Due to technical issues, ALEXA cameras do not support the new motors with the LBUS interface currently (cforce type lens motors).

Frame Grab

• Lazy grab icon on EVF and MON OUT. When you trigger a frame grab, the MON out and EVF status bars will not show a grab icon for the first few seconds. If in doubt, please check the home screen on the camera menu, which immediately shows when the camera takes a frame grab.

• No warning if frame grab failed. If a frame grab is triggered with one of the User buttons (assignable to button 1-3) while no SD card is inserted, the camera will not show a warning.

LDS/LDA

• Alura LDS information drops out during fast adjustments. If the Iris, Zoom or Focus ring on an LDS Alura Zoom is turned very quickly, the corresponding LDS information is lost and the camera will show 'Turn Lens rings!' A slow or normal ring turn recalibrates the lens and brings back the LDS information. Thresholds are (rotation of lens ring end to end) FOCUS: 1.0sec, ZOOM: 0.4sec and IRIS: 0.2sec.

Look Management

• Loading a look file with more than 32 characters When an ALF-2 look file is sent via Ethernet to the camera and the look file name is longer than 32 characters, the camera will load the look file but cannot display the look file's name. It will instead append the current look file's name with an asterisk. This is not a problem when loading the look file from an SD card.

• Corrupt ALF-2 file When scrolling through the list of look files, each file is immediately applied to show the user a preview of the look. If a corrupt ALF-2 file is reached in the list, the default look file is displayed instead without warning. Once the file is enabled, the camera will show a warning.

Metadata

• automatic cropping does not work in postproduction tools Automatic cropping of "black" border in ProRes clips via metadata does not work in software tools that use the AVRI metadata atom.


• LDA produces "random" Lens_SN in metadata field. When the LDA (Lens Data Archive) is used to identify a lens, the camera records a random lens serial number in the metadata. This does not represent the actual serial number of the lens.

Metadata/clip-reel name

• Switching sensor modes resets reel counter to A001 When switching sensor modes, the camera will perform a factory reset. During a factory reset the reel name gets reset to A001.

Miscellaneous

• Interrupted sensor mode switch When power is interrupted during a sensor mode switch a "reset sensor mode" might be needed. That means to set the camera back to 16:9 sensor mode.

• UDPM does not work in ALEXA SXT User defined Pixel Mask does not work in ALEXA SXT. Implementation is planned for future SUP release.

Monitoring

• EVF ZOOM little effects of peaking Peaking with EVF ZOOM enabled is not as effective as without ZOOM.

Playback

• Loading clip for Playback fails Loading a clip from the cliplist for playback may fail even without error message. In this case exit the playback screen, wait for the monitor outputs to show live image and overlays and try again. If that does not work, reboot the camera.

• ARRIRAW border artifacts on playback When SHOW FRAME LINES = OFF in ARRIRAW playback, some image artefacts are visible at the image borders. This is only a playback artifact that is not in the recorded image.

Recording

• Camera takes long to start recording with SxS PRO+ Cards. Compared with an original SxS PRO card (SBP-64A), it takes an ALEXA about 2 seconds longer to start/stop recording with an SxS PRO+ rev B card (SBP-064B and SBP-128B) and about 1 second longer with the latest SxS PRO+ rev C cards (SBP-064C and SBP-128C).

• Recording duration for ProRes clips is limited The maximum file size of ProRes clips is limited. With large drives like the CDX-37021 and i.e. ProRes 4444XQ in HD 1920x1080 at a speed of 23.976 you will have a total capacity of 4 hours 46 minutes but the maximum recording time per clip is limited to 1 hour 12 minutes. This will be shown in STATUS bottom right by two "Remaining time" indications: left is total capacity, right is maximum (real-) time for clip. On HOME in standby will display total capacity, in record maximum (real-) time for clip with a "C" in front of it. After recording is stopped again total capacity is displayed. The camera will stop recording when the limit is reached. Please note that WCU-4 and Web Remote behave differently: they only show the remaining time of the total capacity of the medium and do not show the remaining time for clip.

Recording Media

• Erroneous message - "erasing not possible in this mode"


When trying to erase a recording medium that is not supported by the camera, the camera shows an erroneous message "Erasing not possible in this mode". It should say: "Media not supported".

• XT camera cannot fully format SXT drives If an XR Capture Drive that has been formatted for ProRes on an ALEXA SXT is then placed into an ALEXA XT, the ALEXA XT will only be able to see one of the two internal drives, and will therefore also only be able to format one of the two drives. Data may be left over on the other internal drive from the use in the ALEXA SXT. In order to avoid this, make sure to erase XR Capture Drives by formatting them in the ALEXA SXT or with a Mac at the end of your production.

• Warning is not cleared Warning "W:Media: Temperature high, be careful when handling drive" is not cleared when drive is ejected.

SUP Update

• Problem during power loss while updating If power is lost while performing a Software Update Package update, it is possible that the camera cannot reboot anymore or be updated anymore. In this case it has to be sent to ARRI Service.

Sync

• HD-SDI output sync offset The synced SDI outputs of two cameras in a sensor sync setup may jitter in the range between 0 and 0,1 us (microseconds). Also the offset between the synced SDI outputs may change after settings (i.e. sensor fps) were changed or the camera(s) were rebooted.

• Sensor sync - error if master is started first In a setup with sensor sync, but without settings sync, recording needs to be started first on the slave camera, and then on the master camera. When shooting ARRIRAW, recording on the master camera should be started as quickly as possible after the slave camera. If too much time passes (>2s) after recording has been started on the slave camera, the slave camera will go into an error state as soon as recording is started on the master camera.

• HD-SDI may be out of sync below 7 fps When using Sensor Sync and Settings Sync at frame rates below 7 fps, the HD-SDI outputs may not be in sync.

• HD-SDI may be out of sync at 29.97 psf and 30 psf When using Sensor Sync and Settings Sync and the MON OUT is set to 29.97 psf or 30 psf, the HD-SDI outputs may not be in sync.

Sync/Lens sync

• 3D lens sync does not work In some camera/lens configuration 3D lens sync does not work. This is an intermittent bug that is scheduled to be fixed during the next Software Update Package.

Timecode

• Time Code INT Free Run reset to 00:00:00. With asynchronous recording, i.e. "Project frame rate" NOT EQUAL to "Sensor fps" and time code set to INT FREE RUN, the time code will be reset to 00:00:00 after a reboot.

• TC Break in ARRIRAW 3.2K It is possible that a Timecode break can occur when recording ARRIRAW 3.2K. This does not affect the images.


Usability

• Only 4 user definable frame rates The number of user definable frame rates via FPS > ADD is limited to 4.

• User Button terminates On rare occasions, after switching sensor modes or when rebooting the camera, a message may appear that says "UserButtons has terminated". Power the camera off and on again.

• Some ARRIRAW frame grabs cannot be opened in ARRIRAW Converter ARRIRAW frame grabs in 6:5 ProRes 2K Anamorphic, 4K Anamorphic and OpenGate ProRes 4K Cine currently cannot be processed by the ARRIRAW SDK which is used by the ARRIRAW Converter and other software tools.

User setup

• Additional configuration files User setups do not contain look files, LDA files or custom frame lines. If the look file and/or LDA file is present on SD card it will be loaded and used. Frame lines however need to be loaded manually after loading the user setup.


D. Updating Instructions

Download and Registration Process You have to register your ALEXA camera by serial number to access the Software Update Package (SUP) in the ALEXA DOWNLOADS Section on the ARRI website. A SUP can be installed on the camera either by using an SD card directly on the camera (described in detail below) or from a computer via the ALEXA Ethernet Cable (K2.72021.0). Please note that ALEXA SXT cameras, ALEXA Classic cameras and ALEXA XT/XR cameras require different SUP installation packages.

• Installation packages for ALEXA SXT models are named 'SUP_AlexaSXT_[version-number]‘. • Installation packages for ALEXA Classic models are named 'SUP_Alexa_[version-number]‘. • Installation packages for ALEXA XT/XR model are named 'SUP_AlexaX_[version-number]'.

How to get a Software Update Package • If you have not registered yet, go to the ALEXA DOWNLOADS page at

http://www.arri.com/alexa/downloads and scroll to the 'ALEXA Software Update Package x.x' section (where ‘x.x’ is the version number of the desired Software Update Package). Click 'Please -> register to get an account.' The ALEXA customer registration page will be opened.

• Fill in the relevant data and make sure to put in the serial number(s) of your camera(s) in the format of K1.0006178-xxxx, K1.0006383-xxxx, K1.0006987-xxxx, etc. Don't forget to agree to the registration terms at the end of the page.

• When you hit the 'create account' button the system will send you an acknowledgement email with a link for the activation of your account. After following the link a welcome mail is sent to you containing the login credentials. Please login at http://www.arri.com/login/login.html and navigate to the download section again.

• Upon access of the software package download you will be asked to agree to the terms and conditions of this download. If you agree to these terms the download link is released.

Camera Update Procedure via SD Card Using the SD card for updating is the easiest method. It updates the ALEXA camera as well as the Electronic Viewfinder (EVF-1) as long as the viewfinder is connected to the camera.

Precautions • Make sure the power supply of the camera is stable. The best way to achieve this is by using a main

power supply attached to the battery socket. We do not recommend updating a camera that is powered from a battery.

Preparing the SD Card • Have a FAT16 or FAT32 formatted SD-Card ready. • Cards larger than 4 GB are not supported. If you have a larger

SD card, you need to create one partition with max. 4GB so it will be compatible with ALEXA.

• Go to MENU > SYSTEM > SD CARD and choose - ‘Prepare SD card’ to create the ALEXA folder structure on the SD card, and keep the existing data. - ‘Format + prepare SD card’ to DELETE ALL DATA on the SD card before creating the ALEXA folders.

• Copy the update package SUP_AlexaSXT_x.x_zzzzz.pkg (for ALEXA SXT) or SUP_AlexaX_x.x_zzzzz.pkg (for ALEXA XT/XR) or SUP_Alexa_x.x_zzzzz.pkg (for ALEXA Classic) into the ‘Firmware’ folder on the SD card.

Performing the Update • Turn the camera on.

http://www.arri.com/alexa/downloads

http://www.arri.com/login/login.html


• Perform a factory reset in MENU > USER SETUPS > FACTORY RESET. • Insert the SD card into the SD card slot of the camera. The slot is located below the display on the bottom

of the camera, covered by a slider. The direction how the SD card has to be inserted is shown on the camera housing.

• A card icon will show up in the notification area of the camera display. If not, the card is not recognized by the camera.

• Go to MENU > SYSTEM > FIRMWARE. • The FIRMWARE screen shows you which package is currently installed (Current version: xxx). • Press the jog wheel to select an update file. The list shows all SUP files that are available on the SD card. • Choose the desired package and press the two lower outer screen buttons simultaneously to start the

update. • Caution: Do not remove the SD card while the package is being copied to the camera! • When the ‘copying files’ message disappears the SD card can be safely removed. • The update process may take 15 to 20 minutes, depending on the actual software package Wait until the

update process has finished. This is indicated by a green screen informing you that the update process is completed.

• If the update process fails, which will be indicated by a red screen, please restart the camera and repeat the update procedure.

• After the update, turn the camera off by holding down the power button for a few seconds. • Turn the camera back on. The software is now updated and you can use the camera.

Camera Update Procedure using a Web Browser on your Computer

How to connect ALEXA to a computer • Turn the camera on. • Connect the Ethernet port of the computer to the camera with the ALEXA Ethernet/RJ-45 Cable

(1) 4:3 sensor mode is only available in the following ALEXA Classic cameras: ALEXA Plus 4:3, ALEXA M and ALEXA Studio (2) ProRes is a variable bit rate codec. While it is usually close to the target data rate, the actual data rate can vary with image content. (3) The ALEXA ProRes target data rate is the Apple target data rate plus metadata and other overhead. (4) DNxHD requires the purchase of a DNxHD license for ALEXA, ALEXA Plus andf ALEXA M; a DNxHD license is included in ALEXA Plus 4:3 and ALEXA Studio. (5) The remaining time indicated by the camera is always calculated based on the theoretical maximum data rate, not the target data rate, to be on the safe side.
